Population Growth and Other Statistics of Middle-sized Irish Towns. General Research Series Paper No. 85, April 1976
The basic aim of the study is the presentation of tables of comparative
statistical data relating to 97 towns with population 5OO-1O,OOO in
1971 and analyses of such data. The exclusion of the four County Boroughs
and Dun Laoghaire together with twelve other large towns and all small
towns and villages, was to impart a degree of homogeneity to the inquiry, as
regards function of town. The 97 towns range from Mullingar, the largest
with a population of 9,245 to Cootehill with 1,542
Fermi Liquids and the Luttinger Integral
The Luttinger Theorem, which relates the electron density to the volume of
the Fermi surface in an itinerant electron system, is taken to be one of the
essential features of a Fermi liquid. The microscopic derivation of this result
depends on the vanishing of a certain integral, the Luttinger integral , which is also the basis of the Friedel sum rule for impurity models,
relating the impurity occupation number to the scattering phase shift of the
conduction electrons. It is known that non-zero values of with
, occur in impurity models in phases with non-analytic low
energy scattering, classified as singular Fermi liquids. Here we show the same
values, , occur in an impurity model in phases with regular
low energy Fermi liquid behavior. Consequently the Luttinger integral can be
taken to characterize these phases, and the quantum critical points separating
them interpreted as topological.Comment: 5 pages 7 figure
Examining Mental Health and Well-being Provision in Schools in Europe: Methodological Approach
Schools are considered an ideal setting for community-based mental health and well-being interventions for young people. However, in spite of extensive literature examining the effectiveness of such interventions, very few studies have investigated existing mental health and well-being provision in schools. The current study aims to extend such previous research by surveying primary and secondary schools to investigate the nature of available provision in nine European countries (Germany, Ireland, the Netherlands, Poland, Serbia, Spain, Sweden, the UK and Ukraine). Furthermore, the study aims to investigate potential barriers to mental health and well-being provision and compare provision within and between countries
Intoxicated eyewitnesses:the effect of a fully balanced placebo design on event memory and metacognitive control
Few studies have examined the impact of alcohol on metacognition for witnessed events. We used a 2x2 balanced placebo design, where mock-witnesses expected and drank alcohol, did not expect but drank alcohol, did not expect nor drank alcohol, or expected but did not drink alcohol. Participants watched a mock-crime in a bar-lab, followed by free recall and a cued-recall test with or without the option to reply ‘don’t know’ (DK). Intoxicated mock-witnesses’ free recall was less complete but not less accurate. During cued-recall, alcohol led to lower accuracy, and reverse placebo participants gave more erroneous and fewer correct responses. Permitting and clarifying DK responses was associated with fewer errors and more correct responses for sober individuals; and intoxicated witnesses were less likely to opt out of erroneous responding to unanswerable questions. Our findings highlight the practical and theoretical importance of examining pharmacological effects of alcohol and expectancies in real-life settings
Bursts in a fiber bundle model with continuous damage
We study the constitutive behaviour, the damage process, and the properties
of bursts in the continuous damage fiber bundle model introduced recently.
Depending on its two parameters, the model provides various types of
constitutive behaviours including also macroscopic plasticity. Analytic results
are obtained to characterize the damage process along the plastic plateau under
strain controlled loading, furthermore, for stress controlled experiments we
develop a simulation technique and explore numerically the distribution of
bursts of fiber breaks assuming infinite range of interaction. Simulations
revealed that under certain conditions power law distribution of bursts arises
with an exponent significantly different from the mean field exponent 5/2. A
phase diagram of the model characterizing the possible burst distributions is
constructed.Comment: 9 pages, 11 figures, APS style, submitted for publicatio
In Stories We Trust: Studies of the Validity of Autobiographies
There is a dearth of research addressing the validity of life stories, or autobiographies. In part, this is because it is unclear how such data sources might be validated. This article recommends two differ-ent perspectives for obtaining evidence relevant to the validity of autobiographical data. A study is conducted from each of these perspectives, and multiple validity estimates are obtained in each in-vestigation. The construct validity of standard psychological constructs (e.g., assertiveness, trustwor-thiness) obtained in Study 1 from autobiographies was equal to that of standard instruments designed to assess these constructs. Evidence for the validity of life themes, extracted from autobi-ographies in Study 2, was also apparent. Because life histories, autobiographies, and case studies are relied on heavily in the practice of counseling psychology and are rapidly regaining popularity in scientific studies, these positive findings suggest the wisdom in this increasing use of life history data
